>>203932You mean you want to take photos of the hiking path itself? I guess I don't this kind of thing as being a very interesting photo, but a 35mm equivalent lens will suffice for a photo like that.
>>203936http://www.amazon.com/dp/B00111UX40/ is the filter I used for
>>203929. All the filter does is darken the image so you can take a really long exposure. Not useable with point-and-shoots.
However, you can get a filter attachment for the s90/95/100/110 series of cameras made by Lensmate
